In at least one example embodiment, the apparatus causes display of information, the causation of display may comprise displaying the information on a display comprised by the apparatus, sending the information to a separate apparatus, and/or the like. For example, the apparatus may send the information to a separate display, to a computer, to a laptop, to a mobile apparatus, and/or the like. For example, the apparatus may be a server that causes display of the information by way of sending the information to a client apparatus that displays the information. In this manner, causation of display of the information may comprise sending one or more messages to the separate apparatus that comprise the information, streaming the information to the separate apparatus, and/or the like. The electronic apparatus may comprise an input device 13. Input device 13 may comprise a light sensor, a proximity sensor, a microphone, a touch sensor, a force sensor, a button, a keypad, a motion sensor, a magnetic field sensor, a camera, and/or the like. A touch sensor and a display may be characterized as a touch display. In an embodiment comprising a touch display, the touch display may be configured to receive input from a single point of contact, multiple points of contact, and/or the like. In such an embodiment, the touch display and/or the processor may determine input based, at least in part, on position, motion, speed, contact area, and/or the like. In at least one example embodiment, the apparatus receives an indication of an input. The apparatus may receive the indication from a sensor, a driver, a separate apparatus, and/or the like. The information indicative of the input may comprise information that conveys information indicative of the input, indicative of an aspect of the input indicative of occurrence of the input, and/or the like.

The electronic apparatus 10 may include any of a variety of touch displays including those that are configured to enable touch recognition by any of resistive, capacitive, infrared, strain gauge, surface wave, optical imaging, dispersive signal technology, acoustic pulse recognition, or other techniques, and to then provide signals indicative of the location and other parameters associated with the touch. Additionally, the touch display may be configured to receive an indication of an input in the form of a touch event which may be defined as an actual physical contact between a selection object (e.g., a finger, stylus, pen, pencil, or other pointing device) and the touch display. Alternatively, a touch event may be defined as bringing the selection object in proximity to the touch display, hovering over a displayed object or approaching an object within a predefined distance, even though physical contact is not made with the touch display. As such, a touch input may comprise any input that is detected by a touch display including touch events that involve actual physical contact and touch events that do not involve physical contact but that are otherwise detected by the touch display, such as a result of the proximity of the selection object to the touch display. A touch display may be capable of receiving information associated with force applied to the touch screen in relation to the touch input. For example, the touch screen may differentiate between a heavy press touch input and a light press touch input. In at least one example embodiment, a display may display two-dimensional information, three-dimensional information and/or the like.

In at least one example embodiment, the camera module may further comprise a processing element such as a co-processor that assists the processor 11 in processing image data and an encoder and/or decoder for compressing and/or decompressing image data. The encoder and/or decoder may encode and/or decode according to a standard format, for example, a Joint Photographic Experts Group (JPEG) standard format.

FIGS. 2A-2F are diagrams illustrating a pendant apparatus according to at least one example embodiment. The examples of FIGS. 2A-2F are merely examples and do not limit the scope of the claims. For example, size of the apparatus may vary, the shape of the apparatus may vary, the configuration of the apparatus may vary, and/or the like.

In some circumstances, it may be desirable to configure an electronic apparatus as a pendant apparatus. For example, configuration of an electronic apparatus as a pendant apparatus may permit a user of the electronic apparatus to easily transport the apparatus, wear the apparatus, interact with the apparatus, and/or the like. A pendant apparatus may refer to an electronic apparatus, such as an electronic apparatus similar as described regarding FIG. 1, comprising a pendant form factor. For example, an apparatus comprising a pendant form factor may comprise provisions for attaching the pendant apparatus to a necklace, easily handling the apparatus in the hand of a user, standing the apparatus upright on a table, and/or the like. In at least one example embodiment, a pendant apparatus comprises a necklace.

In some circumstances, it may be desirable for a pendant apparatus to comprise a display. For example, it may be desirable to display information to a user of the pendant apparatus. It may be desirable, in some circumstances, for a display comprised by a pendant apparatus to be a near eye display. For example, a near eye display may allow for the size of the apparatus to remain compact, allow for a user to view the display at a near distance with clarity, and/or the like. In at least one example embodiment, a pendant apparatus comprises a near eye display. In some circumstances, the pendant apparatus may be configured such that the near eye display is best viewed by a single eye of the user. In circumstances such as these, the pendant apparatus may be referred to as a monocular apparatus.

In some circumstances it may be desirable for a pendant apparatus to comprise multiple displays. For example, a pendant apparatus may be configured as a binocular apparatus. A binocular apparatus may refer to an electronic apparatus in which a first display is configured for viewing by a left eye of a user and a second display is configured for viewing by a right eye of a user, such that the displays may be viewed simultaneously by the user.

In some circumstances, it may be desirable for a pendant apparatus to receive environmental sensor information. For example, the apparatus may determine an apparatus orientation, a user input, an apparatus mode, and/or the like by receiving environmental sensor information from at least one environmental sensor. An environmental sensor may refer to an input device similar as described regarding FIG. 1. For example, an environmental sensor may be a touch sensor, an orientation sensor, an accelerometer sensor, an infrared sensor, an optical sensor, a proximity sensor, a gyro sensor, a magnetometer sensor, an inertial sensor, and/or the like.

The examples of FIG. 2A-2C are diagrams illustrating apparatus 200 according to at least one example embodiment. FIG. 2A is a perspective view, FIG. 2B is a front view, and FIG. 2C is a cutaway view of the same example. In the example of FIGS. 2A-2C, apparatus 200 comprises enclosure 202, display 204, environmental sensors 206, 208, 210, 212, 214, 216, 218, 220, 222, 224, 226, and 228, and processor 230. The example of FIGS. 2A-2C depict apparatus 200 as a pendant apparatus, but it should be understood that apparatus 200 may be any type of electronic apparatus.

In some circumstances, a user may have an electronic apparatus similar as described regarding FIGS. 2A-2C under his control. In circumstances such as these, the apparatus may receive a notification of a message, a calendar alert, and/or the like. It may be desirable in circumstances such as these for the viewer to actively view the apparatus to perceive the notification, dismiss the alert, and/or the like. For example, the user may place the apparatus near his eyes, face the apparatus in his direction, and/or the like to actively view the apparatus. During active viewing of the apparatus, a user may be focusing his attention on the apparatus, interacting with the apparatus, and/or the like. For example, during an active viewing of the apparatus, a user may be actively reading information displayed on a display comprised by the apparatus.

FIG. 2D is a diagram illustrating user 240 actively viewing a display comprised by apparatus 242. Even though the example of FIG. 2D depicts apparatus 242 as a pendant apparatus, apparatus 242 may be any type of electronic apparatus.

As previously described, in some circumstances, a user may have an electronic apparatus similar as described regarding FIGS. 2A-2C under his control. In some circumstances, an apparatus may be positioned such that the apparatus may not be actively viewed by the user. For example, the apparatus may be placed on a desk, placed in the user's pocket, worn on the user's body, and/or the like. In circumstances such as these, a display comprised by an apparatus may be passively viewed by a user of the apparatus. During passive viewing of the apparatus, a user may be focusing his attention on something other than the apparatus, ignoring the apparatus, viewing the apparatus with his peripheral vision, viewing the apparatus from a distance, and/or the like. For example, during passive viewing of the apparatus, a user may be reading information displayed on a display comprised by a different apparatus, performing a task independent of the apparatus, and/or the like. In this manner, an apparatus that is being passively viewed is not being actively viewed.

FIG. 2E is a diagram illustrating user 244 passively viewing a display comprised by apparatus 246. Even though the example of FIG. 2E depicts apparatus 244 as a pendant apparatus, apparatus 244 may be any type of electronic apparatus. It can be seen that apparatus 246 is attached to a necklace worn by user 244. Even though the example of FIG. 2E depicts apparatus 246 as being worn by user 244, apparatus 246 may be attached to user 244's clothing, carried in a pocket, carried in user 244's hand, and/or the like, such that apparatus 246 may be passively viewed by user 244.

FIG. 2F is a diagram illustrating user 250 sitting at desk 252 passively viewing a display comprised by apparatus 254. Even though the example of FIG. 2F depicts apparatus 254 as a pendant apparatus, apparatus 254 may be any type of electronic apparatus. It can be seen that apparatus 254 is positioned upright on the top surface of desk 252. Even though the example of FIG. 2E depicts apparatus as upright on the top surface of desk 252, apparatus 254 may positioned in other positions such that apparatus 254 may be passively viewed by user 250. For example, apparatus 254 may be placed upright on a floor surface, laying on a side of apparatus 254 on top of a surface of desk 252, and/or the like.

As previously described, a user may be actively viewing an apparatus. For example, the user may be interacting with the apparatus in a manner similar to user 240 of FIG. 2D interacting with apparatus 242. In circumstances such as these, it may be desirable for an apparatus to enter an active viewing state of the apparatus. For example, an apparatus may determine that the apparatus is being actively viewed by a user based, at least in part, on the active viewing state of the apparatus. An active viewing state may be characterized by a state in which the apparatus is configured in a manner that avoids visual impairment compensation. Visual impairment compensation may refer to the rendering of visual information in a manner that it is easier to perceive and/or comprehend when viewing conditions are less than ideal. For example, visual information rendered with visual impairment compensation may be rendered with a lower pixel resolution, with a higher brightness level, without textual information, and/or the like. Alternatively, visual information rendered without visual impairment compensation may be rendered with an increased pixel resolution, with a lower brightness level, with textual information, and/or the like.

As previously described, a user may be passively viewing an apparatus, not viewing an apparatus, and/or the like. For example, the apparatus may be passively viewed similar as described regarding FIGS. 2E-2F. In circumstances such as these, the user may transition from passive to active viewing. For example, a user may move the apparatus from a position similar as depicted in FIG. 2E or 2F to a position similar as depicted in FIG. 2D. In circumstances such as these, it may be desirable for an apparatus to enter an active viewing state of the apparatus, based, at least in part, on environmental sensor information. For instance, environmental sensor information may indicate that the apparatus is actively viewed by a user. For example, environmental sensor information may indicate that the apparatus has an apparatus orientation with respect to a user. In such an example, the apparatus orientation may be similar to the orientation of apparatus 242 of FIG. 2D with respect to user 240. In at least one example embodiment, the apparatus enters an active viewing state of the apparatus based, at least in part, on the determination that the environmental sensor information indicates that the apparatus is actively viewed by the user.

In some circumstances, an orientation of the apparatus may indicate that the apparatus is actively viewed by the user. For example, the apparatus may be oriented such that a display comprised by the apparatus is in a position in which the view is unobscured. For instance, the orientation of the apparatus when being actively viewed may be similar to the orientation of apparatus 242 of FIG. 2D. In circumstances such as these, it may be desirable for environmental sensor information to indicate that the apparatus is actively viewed by the user based, at least in part, on the orientation of the apparatus. In at least one example embodiment, determination that the environmental sensor information indicates that the apparatus is actively viewed by a user comprises determination that an orientation of the apparatus indicates that the apparatus is actively viewed by the user. In some circumstances, the direction of gravity in relation to an apparatus may indicate may indicate that apparatus is actively viewed by a user. For example, the apparatus may be actively viewed if the direction of gravity substantially parallel to a surface of a display comprised by the apparatus. For instance, it can be seen that the direction of gravity in FIG. 2D is substantially parallel to the display of apparatus 242. In at least one example embodiment, environmental sensor information comprises information indicative of a direction of gravity in relation to the apparatus. In at least one example embodiment, the direction of gravity is substantially parallel to the surface of the display in circumstances where the direction of gravity deviates from being exactly parallel to the surface of the display within a predetermined threshold angle. In at least one example embodiment, the threshold angle is a predetermined angle, such as 15 degrees, 28 degrees, 45 degrees, and/or the like. In at least one example embodiment, the threshold angle varies based on one or more physical characteristics of the apparatus, such as the size of the apparatus, resolution of the display, obscurance of the display by a housing of the apparatus, and/or the like. In at least one example embodiment, the threshold angle may be based, at least in part, on other environmental circumstances, such as the distance between the apparatus and the user, contact between the user and the apparatus, and/or the like. For example, the threshold angle may be larger when the user is further from the apparatus, when the apparatus is larger in size, and/or the like. In another example, the threshold angle may be smaller when the user is closer to the apparatus, when the apparatus is smaller in size, and/or the like.

In some circumstances, an eye of a user proximate to a display comprised by an apparatus may indicate that the apparatus is actively viewed by the user. For example, the display may be a near eye display. A user actively viewing a near eye display may have their eye proximate to the display in a similar manner to user 240's eye being proximate to apparatus 242 of FIG. 2D. In circumstances such as these, it may be desirable for environmental sensor information to indicate that the apparatus is actively viewed by the user based, at least in part, a determination that an eye of the user is proximate to the display. For example, the environmental sensor may be a proximity sensor, an infrared sensor, a sonar, a radar, a capacitive sensor, a light sensor, and/or the like, comprised by the apparatus. In at least one example embodiment, determination that the environmental sensor information indicates that the apparatus is actively viewed by a user comprises determination that an eye of the user is proximate to the display. In at least one example embodiment, the environmental sensor information comprises proximity sensor information that indicates proximity of the user in relation to the display. In at least one example embodiment, the proximity sensor information indicates proximity of the user in circumstances where the proximity sensor information indicates an object being within a threshold distance from the display. In at least one example embodiment, the threshold distance is a predetermined distance, such as 2 centimeters, 4 centimeters, 8 centimeters, and/or the like. In at least one example embodiment, the threshold distance varies based on one or more physical characteristics of the apparatus, such as the size of the apparatus, resolution of the display, obscurance of the display by a housing of the apparatus, and/or the like. In at least one example embodiment, the threshold distance may be based, at least in part, on other environmental circumstances, such as the distance between the apparatus and the user, contact between the user and the apparatus, and/or the like. For example, the threshold distance may be larger when the user is further from the apparatus, when the apparatus is larger in size, and/or the like. In another example, the threshold distance may be smaller when the user is closer to the apparatus, when the apparatus is smaller in size, and/or the like.

In some circumstances, a user holding an apparatus may indicate that the apparatus is actively viewed by the user. For example, a user may necessarily hold an apparatus while interacting with software associated with the apparatus. For instance, the apparatus may comprise touch sensors as an input for software control. A user actively viewing an apparatus may hold the apparatus in a similar manner to user 240 holding apparatus 242 of FIG. 2D. In circumstances such as these, it may be desirable for environmental sensor information to indicate that the apparatus is actively viewed by the user based, at least in part, on determination that the user is holding the apparatus. In at least one example embodiment, determination that the environmental sensor information indicates that the apparatus is actively viewed by a user comprises determination that the user is holding the apparatus. In at least one example embodiment, the environmental sensor information comprises touch sensor information indicative of a user holding the apparatus.

In some circumstances, it may be desirable to determine that an apparatus is actively viewed by a user based, at least in part, on a combination of environmental sensor information received from different environmental sensors. For instance, environmental sensor information may indicate that the apparatus is being actively viewed when no active viewing is occurring. For example, a user may briefly hold an apparatus to move it out of his way, or the apparatus may have an orientation consistent with viewing of the apparatus even though the apparatus is not being actively viewed. In circumstances such as these, the apparatus may determine that an apparatus is actively viewed by a user if a combination of environmental sensor information received from different environmental sensors is consistent with being actively viewed by a user. For example, the apparatus may determine that it is being actively viewed if it has a particular orientation and is simultaneously being held, if the apparatus is being held and the apparatus is proximate to the eye of the user, and/or the like.

As previously described, a user may be passively viewing an apparatus, not viewing an apparatus, and/or the like. For example, the apparatus may be passively viewed similar as described regarding FIGS. 2E-2F. In circumstances such as these, it may be desirable for an apparatus to enter a passive viewing state of the apparatus. For example, an apparatus may determine that the apparatus is not being actively viewed by a user based, at least in part, on the passive viewing state of the apparatus. A passive viewing state may be an operational state in which information is caused to be displayed in conformance with an impaired-viewing display mode absent display of information in an unimpaired-viewing display mode. A passive viewing state may be characterized by a state in which the apparatus is configured in a manner that provides visual impairment compensation.

As previously described, a user may be actively viewing an apparatus. For example, the user may be interacting with the apparatus in a manner similar to user 240 of FIG. 2D interacting with apparatus 242. In circumstances such as these, the user may transition from active to passive viewing. For example, a user may move the apparatus from a position similar as depicted in FIG. 2D to a position similar as depicted in FIG. 2E or 2F. In circumstances such as these, it may be desirable for an apparatus to enter a passive viewing state of the apparatus, based, at least in part, on environmental sensor information. For instance, environmental sensor information may indicate that the apparatus is not actively viewed by a user. For example, environmental sensor information may indicate that the apparatus has an apparatus orientation with respect to a user similar to the orientation of apparatus 246 of FIG. 2E with respect to user 244, similar to the orientation of apparatus 254 of FIG. 2F with respect to user 250, and/or the like. In at least one example embodiment, the apparatus enters a passive viewing state of the apparatus based, at least in part, on the determination that the environmental sensor information indicates that the apparatus is not actively viewed by the user.

In some circumstances, an orientation of the apparatus may indicate that the apparatus is not actively viewed by the user. For example, the apparatus may be oriented such that a display comprised by the apparatus is in a position in which the view is obscured. For instance, the orientation of the apparatus when being actively viewed may be similar to the orientation of apparatus 246 of FIG. 2E. In circumstances such as these, it may be desirable for environmental sensor information to indicate that the apparatus is not actively viewed by the user based, at least in part, on the orientation of the apparatus. In at least one example embodiment, determination that the environmental sensor information indicates that the apparatus is not actively viewed by a user comprises determination that an orientation of the apparatus indicates that the apparatus is not actively viewed by the user. In at least one example embodiment, the environmental sensor is a magnetometer, and environmental sensor information is indicative of an orientation of the apparatus relative to the magnetic north pole of the Earth. In some circumstances, the direction of gravity in relation to an apparatus may indicate may indicate that apparatus is not actively viewed by a user. For example, the apparatus may not be actively viewed if the direction of gravity substantially perpendicular to a surface of a display comprised by the apparatus. For instance, it can be seen that the direction of gravity in FIG. 2E is substantially perpendicular to the display of apparatus 246, and that the direction of gravity in FIG. 2F is substantially perpendicular to the display of apparatus 254. In at least one example embodiment, the direction of gravity is substantially perpendicular to the surface of the display in circumstances where the direction of gravity deviates from being exactly perpendicular to the surface of the display within a predetermined threshold angle. In at least one example embodiment, the threshold angle may be a predetermined angle, such as 15 degrees, 20 degrees, 45 degrees, and/or the like. In at least one example embodiment, the threshold angle varies based on one or more physical characteristics of the apparatus, such as the size of the apparatus, resolution of the display, obscurance of the display by a housing of the apparatus, and/or the like. In at least one example embodiment, the threshold angle may be based, at least in part, on other environmental circumstances, such as the distance between the apparatus and the user, contact between the user and the apparatus, and/or the like. For example, the threshold angle may be larger when the user is further from the apparatus, when the apparatus is larger in size, and/or the like. In another example, the threshold angle may be smaller when the user is closer to the apparatus, when the apparatus is smaller in size, and/or the like.

In some circumstances, absences of an eye of a user proximate to a display comprised by an apparatus may indicate that the apparatus is not actively viewed by the user. For example, the display may be a near eye display. A user not actively viewing a near eye display may have their eye distant to the display in a similar manner to user 244's eye being distant to apparatus 246 of FIG. 2E, user 250's eye being distant to apparatus 254 of FIG. 2F, and/or the like. In circumstances such as these, it may be desirable for environmental sensor information to indicate that the apparatus is not actively viewed by the user based, at least in part, a determination that an eye of the user is distant to the display. For example, the environmental sensor may be a proximity sensor, an infrared sensor, a sonar, a radar, a capacitive sensor, a light sensor, and/or the like comprised by the apparatus. In at least one example embodiment, determination that the environmental sensor information indicates that the apparatus is not actively viewed by a user comprises determination that an eye of the user is distant to the display. In at least one example embodiment, the proximity sensor information indicates distance from the user in circumstances where the proximity sensor information indicates an object being beyond a threshold distance from the display. In at least one example embodiment, the threshold distance is a predetermined distance, such as 20 centimeters, 30 centimeters, 50 centimeters, and/or the like. In at least one example embodiment, the threshold distance varies based on one or more physical characteristics of the apparatus, such as the size of the apparatus, resolution of the display, obscurance of the display by a housing of the apparatus, and/or the like. In at least one example embodiment, the threshold distance may be based, at least in part, on other environmental circumstances, such as the distance between the apparatus and the user, contact between the user and the apparatus, and/or the like. For example, the threshold distance may be larger when the user is further from the apparatus, when the apparatus is larger in size, and/or the like. In another example, the threshold distance may be smaller when the user is closer to the apparatus, when the apparatus is smaller in size, and/or the like.

In some circumstances, absence of a user holding an apparatus may indicate that the apparatus is not actively viewed by the user. For example, it may be necessary for a user to hold an apparatus to interact with software associated with the apparatus. For instance, the apparatus may comprise touch sensors as an input for software control. A user that is not actively viewing an apparatus may not be holding the apparatus in a similar manner to user 244 not holding apparatus 246 of FIG. 2E, user 250 not holding apparatus 254 of FIG. 2F, and/or the like. In circumstances such as these, it may be desirable for environmental sensor information to indicate that the apparatus is not actively viewed by the user based, at least in part, on determination that the user is not holding the apparatus. In at least one example embodiment, determination that the environmental sensor information indicates that the apparatus is not actively viewed by a user comprises determination that the user is not holding the apparatus. In at least one example embodiment, the environmental sensor information comprises touch sensor information indicative of a user not holding the apparatus.

In some circumstances, it may be desirable to determine that an apparatus is not actively viewed by a user based, at least in part, on a combination of environmental sensor information received from different environmental sensors. For instance, environmental sensor information may indicate that the apparatus is not being actively viewed when active viewing is occurring. For example, a user may briefly pull the apparatus away from his eye, the apparatus may have an orientation inconsistent with viewing of the apparatus even though the apparatus is being actively viewed, and/or the like. In circumstances such as these, the apparatus may determine that an apparatus is not actively viewed by a user if a combination of environmental sensor information received from different environmental sensors is consistent with not being actively viewed by a user. For example, the apparatus may determine that it is not being actively viewed if it has a particular orientation and is simultaneously not being held, if the apparatus is not being held and the apparatus is distant from the eye of the user, and/or the like.

FIGS. 3A-3C are diagrams illustrating receipt of input according to at least one example embodiment. The examples of FIGS. 3A-3C are merely examples and do not limit the scope of the claims. For example, the type of input may vary, the number of inputs may vary, the apparatus receiving the input may vary, and/or the like.

As previously described, an apparatus may receive information indicative of an input. For example, the apparatus may receive information indicative of an input from one or more sensors. In circumstances such as these, it may be desirable for the apparatus to comprise the input sensors. For example, a user may perform physical manipulations of an apparatus comprising input sensors to interact with software controlled by the apparatus. In at least one example embodiment, an input sensor may be an environmental sensor. For example, an input sensor may be an environmental sensor similar as described regarding FIGS. 2A-2F.

FIG. 3A is a block diagram illustrating apparatus 300. In the example of FIG. 3A, apparatus 300 comprises processor 301, accelerometer sensor 302, gyro sensor 303, magnetometer sensor 304, proximity sensor 305, touch sensors 306-309, and electrodes 310-317. In the example of FIG. 3A, apparatus 300 may be an apparatus similar to the apparatus described regarding FIG. 1 and FIGS. 2A-2F. It should be understood that in the example of FIG. 3A, processor 301 may receive information indicative of an input from accelerometer sensor 302, gyro sensor 303, magnetometer sensor 304, proximity sensor 305, touch sensors 306-309, and/or the like. As can be seen in the example of FIG. 3A, each touch sensor may receive information indicative of a touch input from one or more electrodes. For example, touch sensor 306 may receive information indicative of a touch input from electrode 310 and/or electrode 311, touch sensor 307 may receive information indicative of a touch input from electrode 312 and/or electrode 313, touch sensor 308 may receive information indicative of a touch input from electrode 314 and/or electrode 315, and touch sensor 309 may receive information indicative of a touch input from electrode 316 and/or electrode 317. Although the example of FIG. 3A depicts each touch sensor being associated with two electrodes, each touch sensor may be associated with any number of electrodes.

In at least one example embodiment, information indicative of an input comprises information indicative of a touch input. In such an example, an apparatus, such as apparatus 300 of FIG. 3A, may detect a user touching the apparatus by way of a touch sensor, such as a user touching one or more of electrodes 306-317 of apparatus 300. Information indicative of a touch input may comprise information indicative of a contact area of the apparatus. For example, electrodes may be positioned at various points on the apparatus. For instance, the electrodes may be placed at various positions on the apparatus similar as described regarding the positions of environmental sensors 206, 208, 210, 212, 214, 216, 218, 220, 222, 224, 226, and 228 of apparatus 200 in the examples of FIGS. 2A-2C. In this manner, the apparatus may determine a contact area of the apparatus based, at least in part, on a contact area of the apparatus pinched or grasped by the user.

FIG. 3B is a diagram illustrating apparatus 322 grasped by user 320. Apparatus 322 may be similar as described regarding FIG. 1, FIGS. 2A-2F, FIG. 3A, and/or the like. FIG. 3C is a diagram illustrating apparatus 332 grasped by user 330. Apparatus 332 may be similar as described regarding FIG. 1, FIGS. 2A-2F, FIG. 3A, and/or the like.

In some circumstances, it may be desirable to provide various manners in which a user may interact with the apparatus by way of a touch input. For example, a user may use a particular touch input to make a particular indication to the apparatus, such as an affirmative response to a prompt, and the user may use a different touch input to make a different indication to the apparatus, such as a negative response to a prompt. For instance, a user may enter a pinch input to designate an affirmative response and a tap input to designate a negative response. Such touch inputs may be natural and intuitive to a user given the shape of the apparatus, the manner in which the user may hold the apparatus during use, and/or the like. In at least one example embodiment, information indicative of a touch input comprises information indicative of a pinch input. In such an example, an apparatus may be pinched by a user similar to user 320 pinching apparatus 322 in the example of FIG. 3B. In this manner, the apparatus may determine that the pinching of the apparatus by the user is a pinch input. In at least one example embodiment, information indicative of a touch input comprises information indicative of a grasp input. In such an example, an apparatus may be grasped by a user similar to user 330 grasping apparatus 332 in the example of FIG. 3B. In this manner, the apparatus may determine that the grasping of the apparatus by the user is a grasp input. In at least one example embodiment, information indicative of a touch input comprises information indicative of a tap input. In at least on example embodiment, a tap input refers to touching a touch sensor for a period below a threshold amount of time. For example, in some circumstances, the apparatus may detect a touch input received by a touch sensor for less than one second as a tap input. In other circumstances, the apparatus may detect a touch input received by a touch sensor for longer than one second as an input other than a tap input. In at least one example embodiment, a tap input refers to a physical disturbance of an apparatus that is detectable by an input sensor. For example, apparatus 320 of FIG. 3B may detect a user bumping apparatus 320 against his palm. Such a bumping of the palm may be detected by an input sensor, for example an accelerometer sensor, as a tap input.

FIG. 4 is a diagram illustrating receipt of input according to at least one example embodiment. The example of FIG. 4 is merely an example and does not limit the scope of the claims. For example, the type input may vary, the number of inputs may vary, the apparatus receiving the input may vary, and/or the like.

As previously described, an apparatus may receive information indicative of an input from one or more input sensors. In some circumstances, it may be desirable to receive information indicative of an apparatus movement input. For instance, a user of the apparatus may wish to interact with an apparatus with an input other than a touch input, interact with the apparatus with movement of the apparatus in conjunction with touch inputs, and/or the like. In this manner, the apparatus may be utilized similar to other devices the user may be familiar with, such as a monocular apparatus. For example, it may be intuitive for a user to scroll through a software screen controlled by the apparatus without having to utilize touch input by “tilting” the apparatus, identify objects for selection by “pointing” the apparatus at an object, and/or the like. In at least one example embodiment, information indicative of an input is indicative of an apparatus movement input.

FIG. 4 illustrates apparatus 400 in relation to vertical axis 402, lateral axis 404, and longitudinal axis 406. Apparatus 400 may be similar as described regarding FIG. 1, FIGS. 2A-2F, FIG. 3 and/or the like. FIG. 4 illustrates a rotational movement 412, a rotational movement 414, and a rotational movement 416. In the example of FIG. 4, rotational movement 412 is an example of a rotational movement with respect to vertical axis 402. In the example of FIG. 4, rotational movement 414 is an example of a rotational movement with respect to lateral axis 404. In the example of FIG. 4, rotational movement 416 is an example of a rotational movement with respect to longitudinal axis 406.

In some circumstances, an apparatus may be moved up and/or down with respect to the current position of the apparatus. For example, apparatus 400 of FIG. 4 may be moved up and/or down along vertical axis 402. Movement up and/or down may be referred to as a vertical movement. In at least one example embodiment, an apparatus movement input is indicative of a vertical movement. An apparatus movement input indicative of a vertical movement, for example, an upward movement, a downward movement, and/or the like, may be referred to as a vertical input.

In some circumstances, an apparatus may be moved left and/or right with respect to the current position of the apparatus. For example, apparatus 400 of FIG. 4 may be moved left and/or right along lateral axis 404. Movement left and/or right may be referred to as a lateral movement. In at least one example embodiment, an apparatus movement input is indicative of a lateral movement. An apparatus movement input indicative of a lateral movement, for example, a leftward movement, a rightward movement, and/or the like, may be referred to as a lateral input.

In some circumstances, an apparatus may be moved forward and/or backward with respect to the current position of the apparatus. For example, apparatus 400 of FIG. 4 may be moved forward and/or backward along longitudinal axis 406. Movement forward and/or backward may be referred to as a longitudinal movement. In at least one example embodiment, an apparatus movement input is indicative of a longitudinal movement. An apparatus movement input indicative of a longitudinal movement, for example, a forward movement, a backward movement, and/or the like, may be referred to as a longitudinal input.

In some circumstances, an apparatus may be rotated about a vertical axis with respect to the current position of the apparatus. For example, apparatus 400 of FIG. 4 may be rotated similar to rotation movement 412. Rotation about a vertical axis may be referred to as a yaw movement. In at least one example embodiment, an apparatus movement input is indicative of a yaw movement. An apparatus movement input indicative of a yaw movement, for example, a leftward yaw rotation, a rightward yaw rotation, and/or the like may be referred to as a pan input.

In some circumstances, an apparatus may be rotated about a lateral axis with respect to the current position of the apparatus. For example, apparatus 400 of FIG. 4 may be rotated similar to rotation movement 414. Rotation about a lateral axis may be referred to as a pitch movement. In at least one example embodiment, an apparatus movement input is indicative of a pitch movement. An apparatus movement input indicative of a pitch movement, for example, an upward pitch rotation, a downward pitch rotation, and/or the like, may be referred to as a tilt input.

In some circumstances, an apparatus may be rotated about a longitudinal axis with respect to the current position of the apparatus. For example, apparatus 400 of FIG. 4 may be rotated similar to rotation movement 416. Rotation about a longitudinal axis may be referred to as a roll movement. In at least one example embodiment, an apparatus movement input is indicative of a roll movement. An apparatus movement input indicative of a roll movement, for example a clockwise roll rotation, a counter-clockwise roll rotation, and/or the like may be referred to as a spin input.

In some circumstances, information indicative of an input may be indicative of more than one type of movement input. For example, a user may move an apparatus in multiple directions at once, may rotate the apparatus along more than one axis, may move the apparatus in one or more directions while rotating the apparatus along one or more axes, and/or the like. For instance, a user may move an apparatus upward and leftward, may tilt the apparatus downward while panning the apparatus rightward, may move the apparatus downward while tilting the apparatus upward, and/or the like.

FIG. 5 is a diagram illustrating determination of an operation according to at least one example embodiment. The example of FIG. 5 is merely an example and does not limit the scope of the claims. For example, the type operation may vary, the number of operations may vary, the apparatus determining the operation may vary, and/or the like.

In some circumstances, an apparatus may perform operations. For example, an apparatus may execute software routines, respond to input, control hardware, and/or the like. For instance, a user may be using the apparatus to perform a particular task, to run software, and or the like. In circumstances such as these, particular operations may be associated with the task, the software routine, and/or the like. In some circumstances, it may be desirable for an apparatus to determine an operation based, at least in part, on an input. For example, an apparatus may perform an operation based, at least in part, on a particular input from a user. In this manner, they apparatus may perform an operation based, at least in part, on a desire of the user, execute a particular software routine based, at least in part, on the environmental conditions of the apparatus, and/or the like.

As previously described, in some circumstances, an apparatus may enter a passive viewing state, an active viewing state, and/or the like. In circumstances such as these, it may be desirable to determine an operation based, at least in part, on the viewing state and an input. For instance, user may desire to interact with the apparatus in different manners based, at least in part, on whether the user is actively or passively viewing the apparatus, what information is being displayed by the apparatus, and/or the like. For example, for a user may enter a particular input, such as a tap input, to initiate different operations for different viewing states of the apparatus. For instance, a tap input may be entered to terminate display of a visual event notification when the apparatus has entered a passive viewing state, a tap input may be entered activate a software routine when the apparatus has entered an active viewing state, and/or the like. In another example, it may be desirable for an apparatus movement input to disable a lock mode during a passive viewing state, and cause device interaction during an active viewing state. Lock mode may refer to a mode of an apparatus that limits apparatus functionality. For example, the apparatus may not receive most input until a particular input is used to disable the lock mode, such as a particular gesture, a password, and/or the like. In circumstances such as these, it may be desirable for an apparatus to correlate an operation with a particular input and a particular viewing state.

FIG. 5 illustrates a table correlating various inputs with particular viewing states and operations. The table of FIG. 5 may comprise a data structure, a formatted table, a user readable list, and/or the like, that correlates a particular type of input a particular viewing state and a particular operation. A particular correlation may be retrieved from a repository, generated by a user profile, configured by a user of the apparatus, generated based, and/or the like. In the example of FIG. 5, tilt input 502 is correlated with active viewing state 512 and passive viewing state 532. Active viewing state 512 is correlated with operation 522. Passive viewing state 532 is correlated with operation 542. In the example of FIG. 5, rotation input 504 is correlated with active viewing state 514 and passive viewing state 534. Active viewing state 514 is correlated with operation 524. Passive viewing state 534 is correlated with operation 544. In the example of FIG. 5, pan input 506 is correlated with active viewing state 516 and passive viewing state 536. Active viewing state 516 is correlated with operation 526. Passive viewing state 536 is correlated with operation 546. Even though the example of FIG. 5 illustrates a tilt input, a rotation input, and a pan input, the table in the example of FIG. 5 may comprise correlations for any type of input, any number of inputs, and/or the like. For example, the table may correlate a tap input, a sideways input, a combination of inputs, and/or the like, with a particular viewing state, with a particular operation, and/or the like.

In at least one example embodiment, an apparatus determines an operation based, at least in part, on a passive viewing state and an input. For example, an apparatus may determine operation 542 of FIG. 5 based, at least in part, on receipt of a tilt input 502 after the apparatus has entered a passive viewing state 532. In this manner, the apparatus may perform operation 542 based, at least in part, on tilt input 502 and passive viewing state 532. For example, operation 542 may be a scrolling operation where visual information is scrolled at a reduced rate in proportion to a rate of scrolling of visual information in proportion to an identical input correlated to a different operation, such as operation 522. For instance, if a user is viewing photographs, operation 542 may scroll to a different position of a currently viewed photograph upon receipt of tilt input 502 during an active viewing state, whereas operation 522 may advance to a different photograph within a gallery upon receipt of tilt input 502 during a passive viewing state. In another example, if a user is reading text, operation 542 may scroll the text being read line by line upon receipt of tilt input 502 during an active viewing state, whereas operation 522 may scroll the text being read page by page upon receipt of tilt input 502 during a passive viewing state.

When an apparatus has entered a passive viewing state, it may be desirable for inputs to be based on passive types of operations a user may desire to cause performance of, the context of a user interacting with the apparatus while in a passive viewing state, software being utilized while in a passive viewing state, and/or the like. In at least one example embodiment, the passive viewing state is an operational state in which operations that correlate with inputs and the passive viewing state are tailored to an impaired-viewing display mode. In some circumstances, operations that correlate with inputs and the passive viewing state avoid interaction associated with information displayed in an unimpaired-viewing display mode. For example, operations that correlate with inputs and the passive viewing state may be limited to interaction associated with information displayed in an impaired-viewing display mode, omit causation of display of information in an unimpaired viewing display mode, provide limited user visual interaction associated with the impaired-viewing display mode, and/or the like.

In at least one example embodiment, an apparatus determines an operation based, at least in part, on an active viewing state and an input. For example, an apparatus may determine operation 522 of FIG. 5 based, at least in part, on receipt of tilt input 502 while the apparatus is in active viewing state 512. In this manner, the apparatus may perform operation 522 based, at least in part, on tilt input 502 and active viewing state 512. For example, operation 522 may be a scrolling operation where visual information is scrolled at an increased rate in proportion to a rate the scrolling of visual information in proportion to an identical input correlated to a different operation, such as operation 542. For instance, if a user is viewing photographs, operation 522 may advance to a different photograph within a gallery upon receipt of tilt input 502 during a passive viewing state, whereas operation 542 may scroll to a different position of a currently viewed photograph upon receipt of tilt input 502 during an active viewing state. In another example, if a user is reading text, operation 522 may scroll the text being read page by page upon receipt of tilt input 502 during a passive viewing state, whereas operation 542 may scroll the text being read line by line upon receipt of tilt input 502 during an active viewing state.

When an apparatus has entered an active viewing state, it may be desirable for inputs to be based on active types of operations a user may desire to cause performance of, the context of a user interacting with the apparatus while in an active viewing state, software being utilized while in an active viewing state, and/or the like. In at least one example embodiment, the active viewing state is an operational state in which operations that correlate with inputs and the active viewing state are tailored to the unimpaired-viewing display mode. In some circumstances, operations that correlate with inputs and the active viewing state avoid limited user visual interaction associated with the impaired-viewing display mode. For example, operations that correlate with inputs and the active viewing state may comprise interaction associated with information displayed in an unimpaired-viewing display mode, may cause display of information in an unimpaired-viewing display mode, may provide interaction associated with information displayed in an unimpaired-viewing display mode, and/or the like.

In some circumstances, it may be desirable for an apparatus to preclude performance of an operation based, at least in part, on the passive viewing state and an input For instance, the apparatus may be hanging from a necklace worn by the user, placed in the user's pocket, sitting on a desk, and/or the like. In circumstances such as these, the apparatus may be inadvertently touched, moved, and/or the like. In circumstances where the apparatus is in a passive viewing state, precluding performance of operations may limit undesired operation of the apparatus based, at least in part, on unintended input. For example, when they apparatus is in a passive state, certain movement inputs may be undesirable, a particular operation may not be correlated with a particular input and the passive state, and/or the like. In at least one example embodiment, preclusion of performance of the operation comprises determination of absence of an operation that correlates with the passive viewing state and an input. For example, the apparatus may receive an unintentional tap input while the apparatus is placed within a pocket, and the apparatus may preclude dismissal of a notification based, at least in part, on the unintentional tap input.
